Cask weeping mitigation

摘要

A method (and concomitant kit) for treating a surface to reduce subsequent ¹³⁷Cs nuclide desorption comprising contacting the surface with a first cation-containing solution, the cation being one or more of Cs⁺, Rb⁺, Ag⁺, Tl⁺, K⁺, and NH₄⁺, and contacting the surface with a second cation-containing solution, the cation being one or more of Cs⁺, Rb⁺, Ag⁺, Tl⁺, K⁺, and NH₄⁺, thereby reducing amounts of radioactive cesium embedded in clays found on the surface.
